[Biophysical profile in prolonged pregnancy. Another alternative to fetal monitoring].
The value of the biophysical profile scoring to predict accurate perinatal outcome in prolonged pregnancy, was assessed. 60 patients with the diagnosis of prolonged pregnancy were included in this prospective clinical trial. A fetal biophysical profile score, described by Manning and modified by Johnson, was recorded in all these patients. There were 40 cases (66%) with normal profile scoring 3 of which had a feature considered as perinatal morbidity (specificity 94.8%). In contrast, from 20 cases with abnormal profile scores, 18 (90%) had abnormal perinatal findings (sensitivity 85.7%). The false positive and negative rates were low, 10 and 7.5% respectively, and the global predictive value of this test was 90%. In our study the amniotic fluid volume was the profile variable most able to identify a compromised fetus and the second with the highest specificity. Although we had a high cesarean section rate, (71%), we suggest that with normal profile scores (greater than or equal to 8) and normal amniotic fluid volume, the fetal biophysical profile may be an accurate test in the evaluation of the fetal condition in this obstetric complication.
